What is the purpose of the color-coding of ID cards?

The color coding of ID cards serves primarily to facilitate easy identification from a distance and to clearly indicate different types of access privileges. This system allows security personnel and staff to quickly recognize individuals who are authorized to be in certain areas, which enhances overall safety and security within the facility. By using distinct colors, organizations can streamline access control processes and minimize confusion regarding who can enter specific parts of the premises, thus helping to maintain a secure environment. Additionally, using color coding for access types makes it easier for employees and visitors to understand the limitations of their access rights at a glance.
